Grajeda has been officiating in the Major League Soccer middle since 2004, recently surpassing the 150-game landmark after taking charge of 13 games during the current season.

In 2013, Grajeda was voted Referee of the Year, in a season which saw him also land center assignments for the MLS All-Star Game and the MLS Cup, and this year’s honour is just the latest to be bestowed upon him.
